Watermelons belong to the calabash family, and is a herb with a one-year cycle. Watermelons were originally produced near the equatorial area of Africa. High temperature is suitable for watermelon's growth. In the early 10th century, watermelons were introduced to the western territory of China from west Asia. That's why watermelon was called "xi-gua" (literally translated as west melon)". Immigrants brought watermelon to Taiwan between the last years of the Ming Dynasty and early years of the Chang Dynasty, longer than 200 years ago.

There are large varieties of woodcraft in Da-shi including tables, chairs, and cabinets, as well as the woodcrafts for worship, such as worship-tables, wood altars, and ancestor tablets. Flower stands and brush stands are also available here. Customers from all over Taiwan place orders for export to Japan and USA. Manufacturers import black sandalwood, purple sandalwood, red wood, and teak from Southeast Asia. The same workers cut the wood, join the wood, carve the wood, and apply paint. There is no rush at all, but all works have to be done in a consistent manner. The styles and design are passed down from the Ching Dynasty with emphasis on the traditional sense of beauty.

All woodcrafts made in Da-shi are made of genuine materials. The refined skills and lasting styles truly reveal the perfect their craftsmanship. However, the traditional designs are not flexible in terms of innovation. Prices are higher, too. Production takes a long time. That is why sales have been dropping in recent years, plus there are less and less skilled workers nowadays; all stores are under heavy pressure. Now the manufacturers are looking for a breakthrough by sponsoring exhibitions and contests, and hope to create a fresh air for the old shops. If the styles and purposes can be changed, manufacturers will be able to expect new growth.
